Application filed August 28. 1911. Serial No. 646,439.

To all 'uf/mm it may concern lle it known that I, Janus Barons a citizen of the l nitcd States, residing at Des Moine-t, in the county of Poll; and State of .lowa. have useful Varmrixcr, of which the following is. a specification.

The object of my invention is to provide a vaporizer especially designed for use in Connection with automobiles.

Wore specifically it is my object to provide a vaporizer in which the heat from the engine exhaust pipe is employed for raising the temperature of a chamber to which gzsolene is automatically ted in suitable quantities so that the gasolene may be vaporized by the heat and retained within the chamber at a pressure slightly in excess of atmospheric pressure so that the vapor thus generated may be retained under pressure to be delivered to the engine in such a man ner that the supply of vapor is readily available at all times, even after theengine has remained stationary for a considerable pe riod of time that the engine may be started immediately without waitin tor the vapor to be drawn into it through a vaporizer by suction in the ordinary manner.

A further object is to provide means for automatically maintaining the vapor within the chamber at a certain p 'edetermined degree of pressure and to automatically control the flow of gnsoletic into the chamber by said pressure regulating means.

A further object is to provide means for automatically stopping the flow (it gasolcnc into the chamber when the chamber is being held for a considm'ablc pcz'iod of time in an inclined position as. tor instance. when the automobile i.- standing still on an inclined surface.

My invention consists in certain details. in the construction. arrangement and con bination of the various parts: of the device.

invented a certain new and whereby the objects contemplated are attaincd, as hereinafter more full set forth.

pointed out in my claims and illu trated in the accompanying drawings, in which:

Figure 1 shows a top or plan view (it a vaporizer embodying my invention with the cover of the chamber removed. Fig. 2 shows a sectional view on the line 22 of Fig. 1. Fig. 3 shows an enlarged. detail. sectional view illustrating the float governor and the pressure regulator. Fig. i show an enlarged, detail. sectional viev of the valve to be controlled by the pressure regulator. Fig. 5 shows anenlargcd, detail, sectional view of the pressure regulator. Fig. 6 shows an enlarged. detail view of the butterfly valve for controlling the admission of heated vapors from the exhaust pipe into the heat pipes on the interior of the vaporizing chamber. and Fig. 7 shows an enlarged, detail, sectional view of the valve for controlling the supply of gasolene.

Referring to the accompanying drawings, l have used the reference numeral 10 to indicate a rectangular vaporizing chamber preferably made of sheet metal. Resting on top of same is a gasolene tank 11, the gasolcnc tank being connected with the vaporizing chamber by the gasolene supply pipe 12. The numeral 13 indicates an eX- haust pipe from an internal combustion en'- gine. Connected Will! the exhaust pipe is a pipe 1% for the hot vapors from the exhaust pipe. which pipe ii is provided with a valve casing 17 containing a butterfly valve 1t: controlled by a crank arm 17. The upper end of the pipe 14 communicates with a coupling 18 within the vaporizing chamber having four branches leading from it. (ommunicatingz' with each of the four branches or" the coupling 18 is a heat radiating device ccmprisiizg a SCllC i of pipes 19 so arranged that hot vapors entering the coupling 18 may travel through in one of the pipes l exactly the same distance before rea hing the discharge pipes 20 and 21. Thepre'terrcd arrangement of these lifus is illustrated in Fig. 1 although various other constructions might be used. it being the purpose of this part of iuv device to provide fo the exhaust vapors from the ci'igiue being divided and 'iassing through uch of the rut iatiug pipes. with approxiuralclv the same amount of hot vapors flowing through each pipe so that the entire radiating system is thus heated to the same degree.

All of the pipes comprising the radiat ing s stem are preferably covered with an absorbent material 22 such. for instance as felt, a illustratwl in Fig. 2. The telt covering tor these pipes has been omitted from Fig. 1 so that the pipe may he clearly seen.

Arranged within the bottom ot the. Var,

pcrizinsr chamber is a series of layers of ihsorbcnt material such as felt and they -are arranged in a plane below the radiating pipes 19, the absorbent material of the pipes being preferably placed in position in engagement with the layers of felt 23.

It is essential that the gasolene be main taincd at approximately a certain predetermined'level within the vaporizing chamher so that there is just suflicient gasolene to moisten the layers of felt 23 and the felt that surrounds the radiating pipes.

To provide for the regulation of the gasolene flow, l have arranged in the gasolene pipe 12 a valve 24; which, as illustrated in Fig. 7, is provided with a comparatively small valve opening 25 so arranged that a very slight turn of the valve stem 26 will be sufiicicnt to either cut 0d the flow of gasolcne or open the passageway through the valve. Connected with the valve stem 24.? is an arm 27 to which is connected a float Said parts are so arranged that when the float is elevated by an excessive quantity of liquid within the vaporizing chamber the valve will be closed and when lowered it will be opened.

' which the vaporizer is placed is standing on an inclined surface so that the vaporizer wilhnot be flooded in the event that the vaporizing chamber is tilted in one direction. This device comprises a weighted bell crank lever 29 having a forked end 30 conn cted with the float. The said weighted bell rank lever is so arranged that if the vaporizing chamber is tilted in position with the right end, as shown in Fig. 3, elevated, the weighted lever will tend to close the valve and if the same end is lowered the we ghted lever will eoact with the iieat open the valve. This weigh ted lever counterb-alanced with the float and hence it will only wor to control the valve when the float ,7 to mote downwardly on account of the ab of the supporting liquid in HE}; act vyh it. Therefore the interior of lac tank c: :mot he tlooded when the gcsoleue is in e asement with the lioat but it is only when the tank is tilted in direct-um for ving the gasolene 3W2) from the .lloat t at the weight will operate to open valv in order that t a mixture of vapor and air that. is Fillll'llifnl to the ergine may be heated to the grivtest extent possible so that it will be irv combustible within the engine cylir lei-s. i have provided an air heating means commising jacket 30 surrounding a part o theeugine exhaust pipe 13 and having one end open to admit air and the other end 'rran cd a 'nunication vvini a r X ng' valve 30 which is also connected to the vapor supply pipe 30 which leads from the interior of the vaporizer tank and discharges into the mixing valvr. The mixing valve of itself may be made of any ordinary construction. The advantage of having the mixing valve supplied with heated air to commingle with the heated vapor is that the combined product may be delivered to the engine cylinders in a heated condition so that it is more readily combustible than a cold mixture.

l have also provided means for maintaining the vapor within the vaporizing chamber, at a pressure slightly in excess of atmospheric pressure, and also in this con uection I have provided means for forcing the gasolene into said vaporizing chamber against said pressure as follows: Connected with the gasolene supply pipe 12 is a valve casing 31.

Within the valve casing 31 is a passageway 32 leading to a ball valve chamber 38 on which a ball valve 34 is placed to normally close the passageway by the weight of the ball. Leading from the ball valve chamber 83 is a passageway 35 leading to a chamber 36 in which is slidinglv mounted a piston 37. This piston is provided with a number ofvertical passageways 38 in each of which is a ball valve 3.) held upwardly against the valve seatby a spring so. By this arrangement, it is obvious that when the piston 37 moves downwardly it will create enough suction within the chamber 36 and the/passageway 35 to raise the ball valve fiat-from its seat and to admit a quantity ofgasoleneinto thechamber 36; then when the piston'37 is elevated the gasolene will force the ball valves 39 downwardly and thus permit the gasolene to flow downwardly through the valve into the vaporizing chamber.

Connected to the lower end of the piston 37 is a stem 41, which stem is extended through the regulator disk 42, in which disk a spring 43 to hold the top of the disk 42 elevated. By this arrangement, it is obvious t lat when the vapor pressure within the aporizing chamber increases to a certain point, the top of the disk 42 will be forced downwardly and the piston 37 will be moved downwardly and a fresh supply of gasolene will be introduced into the chamber 36; then when the pressure reduced the spring 43 will elevate the upper portion of the disk 42 and the piston 37 will be forced upwardly, thus forcing a quantity of gasolene from the chamber 36 into the vaporizing chamber.

The amount of heat introduced into the vaporiring chamber controls the generation of vapor and in order to regulate the amount of heat thus admitted, I havevprovided on the stem 41 below the vaporizing chamber a in com- I boll crank lever 4 connected by a rod 45 with the crank 17 of the butterfly valve. By

this arrangement. when the pressure Within the vaporizing chamber becomes too great, the butterfly val e is partly closed and the heated vapors are permitted to escape through the exhaust pipe.

It is to be understood that the vapor from the vaporizing chamber is to be mixed with air in proper proportions in any ordinary vvay before being admitted into the engine.

Que of the advantages of my improvement is that there vvill alxvavs be a quantity of vapor under pressure .:ontained within the vaporizing chamber so that when starting the engine vapor ivill'be admitted into the cylinders on the first piston stroke in proper condition to be ignited and exploded.

Another advantage is that by doing away with small needle'valves and the like for controlling the supply of gasolene, I avoid the danger of having the supply pipes clogged up on account of the presence of minute particles of foreign matter in the supply of gasolene.

Another advantage is that by the generation of vapor in this manner, I am enabled to provide vapor in proper quantities for use in an engine Whether the engine is used in extremely cold Weather or in extremely warm Weather the outside has practically no efi'ect upon the generation of vapor in my improved vaporizer.
